A paper by F. W. King, “Analysis of some integrals arising in the atomic four-electron problem” [J. Chem. Phys. 99, 3622 (1993)], contains expressions which it is shown can be further simplified to an extent making the formulation significantly more efficient. Two errors in one of the equations are also identified.
